IMPROVEMENT IN HARVESTER-GUTTERS.

To ALL WnoM ir -MAY coiu'lnnn;

Be it known that we, WILLIAM N.WH1TELY, Jr., Jnnom: FAssLun, and O. S.KELLY, .of Springfield, in the county of Clark, and `Stat-eV of Ohio,have invented a. new und useful Improvement in Harvesters Cutting Appa-rratus; andwe do hereby declare the following to be a, full, clear, undexact description of the Satine,- reference l 'being had totheaccompanying drawings, in Which"- Figure lis a plan view ofthe cuttingappuratusof a. harvester with our improvement' attached. Figure 2 is a.verticnllongitudinal section of the sume on the line :r

` i 'Thai-nature of our invention consists infan improved constructionof thc nail-rod, whereby the friction nf" thecuttirigupplaratus isreduced, und ull clogging at thc-under side oithe same is-obviated. l

".Thutpothes'may understand its construction andopeiation, We will morefully desoriho'it.

. A is thenger-bnr, audB B the guard-fingers. C Cure sections oi' thecutters 'attached -to the cutter-bur D. As the cutters reciprocate buch'und forth across. the fingers B they nre guided ut the buch bythe frontedge of nger-barA und in front by the rear edge of the' nail-rod E. Thisrod has hitherto been made nt on its upperide," against which Athe underside of thccutters rest. While in operation thc upper Surface of thcnail-rod becomes coated with gummy matter from the stalks of the grussbeing' cut, and as this gummy mutter istinti-lubricant the lnhoi` ofmoving `the cutters.is greatly increased, and sometimes jthe cloggingfrom this V'conse is suicient to arrest the motion of thecnttershentirely-ond bring the. machine to a stand-still. jWth u.nail-'rod of'` the formi ,and position oi: the rod E, this clogging cnn-ncver occur, because, in the first place, the amount of surf-eceexposed is so small that even though it should be covered with gummymutter itwould not i offer any serious impediment to the move'ient ofthe cutters, and in the second place the entire pressure of the cutting`apparatus, which commonly is formed bythe wide surface oi' the nail-rod,i's here concentrated upon the narrow edge F, which' is turned up, alsshown in fig. 2, for .that purpose; The surface friction .being thusproportionately increased renders it proportionately less 4liable topermit the entrance of'lany gummy inatter from the cut grass. The anglefo'ijmed between the lower surface ot' the cutter and the front 'eligeof thefnnil-4 yrod at theirwpoint ojunctionis a. right angle. Theex-trem'e edge of therod E is in contact with tirolo-wer side i ofthe-cutters, and this oiers un obstacle to the entrance oi'fany gumuiymatter, nnohstacle which would not y. ,exist if this angle were lessthanu right angle.

' 1 Having described our invention, what wepclaim asnew, und desire tosecure by Letters Patent, s f i The nail-rod E, provided with theright-angled flange F, substantially as und for the purpose set forth.`l WM. N. WHITELY, JR.,
